First of all, the problems that can be solved in the embodiments of the present disclosure are:

(1) Identification problem

The operator's network is identified through a Public Land Mobile Network ID (PLMN ID). The number of PLMN IDs is limited. An operator network may include a plurality of private communications networks (PVNs) capable of supporting a plurality of vertical services, and a vertical service may span a plurality of operator networks. Therefore, the PLMN ID cannot be used as an identifier for a personal communication network. A personal communication network of one vertical task may include a plurality of network slices, and an identifier associated with a network slice cannot be regarded as an identifier of a personal communication network. Thus, it is not yet clear how a single vertical task will identify a private communication network among operators.

(2) Network type permission of upper layer application

When providing a personal communication network to a vertical service through an operator network, terminals of the vertical service may access the personal communication network to communicate with each other or visit a server of the vertical service. Terminals of vertical industries can simultaneously visit the operator's public communication network and conduct public communication work. In the related art, there is no definable information in the terminal as to which upper-layer applications access the private communication network and which upper-layer applications access the public communication network.

Among them, for the terminal of the type B network, it can only access the private communication network; For a terminal of a type A network, it can access a private communication network and a public communication network.

(3) Movement and roaming range permission

The service coverage of the private communication network may not possibly cover the entire network, but may be a limited area. For a terminal of a vertical service, it is not clear which network area supports the private communication network of the vertical service, that is, it is not clear from where to access the private communication network. For the operator's network, a plurality of private virtual networks can be divided to support personal communication services. It is not yet clear how to select a network element of a personal communication network for a terminal.

Among them, for the network of type B, it has only the mobile range of the personal communication network; For a type A network, it includes the movement range of the private communication network, the movement range of the roaming, and whether or not roaming in the public communication network is permitted.

In addition, for a type A network, when registering in a private communication network, whether to allow access to a public communication network should be announced, and when registering in a public communication network, whether to allow access to a private communication network should be notified.

(4) overall architecture

Currently, when a cell simultaneously supports a private communication network and a public communication network, it is not yet clear which communication network to register first, and a Radio Access Network (RAN) network element has an access management function (Access Management Function, AMF) is not yet clear.

To claim to indicate the personal communication network ID, the UE sends a Radio Resource Control (RRC) request to the RAN. The network must determine the type of registration in conjunction with whether the RAN supports private communication network IDs.

In the embodiments of the present disclosure, several overall architectures are presented, among which, reference is made to FIGS. 1A to 1C for exemplary diagrams of the entire architecture. It should be noted that the slices shown in Figs. 1A to 1C represent network slices.

Overall Architecture 1: As shown in Fig. 1A, a radio access network is shared by each private communication network and a public communication network; AMFs and slices are solely owned by each private communications network and public communications network, that is, each private communications network and public communications network both have dedicated AMFs.

Overall architecture 2: As shown in Fig. 1b, the radio access network and AMF are shared by each private communication network and public communication network; A slice is solely owned by each private communication network and public communication network.

Overall Architecture 3: As shown in Fig. 1c, the radio access network, AMF and slice are all private communication networks and public communication networks respectively.

What needs to be explained is that the multi-selectable implementation methods described in this embodiment can be implemented in combination with each other, or can be implemented alone, and the embodiments of the present disclosure are not limited thereto.

The processing method of this embodiment has at least the following advantageous effects.

Supports operator network information of personal communication networks. To be readily understood, a private communication network of one vertical business may possibly be deployed among a plurality of operators' networks. For user V of personal communication network P, the personal communication network is deployed on operator A and operator B. User V is a card issuing user of operator A, and in case of roaming, user V can support access of operator B's personal communication network. Accordingly, operator network information supporting the personal communication network may be roaming network information associated with the personal communication network. Since the terminal can simultaneously support access to the private communication network and access to the public communication network, roaming network information related to the private communication network and roaming network information of the public communication network may be different.

To be easily understood, a terminal can simultaneously support access of a private communication network and access of a public communication network. The private communications network may possibly share a radio access network with a public communications network. In one embodiment, the terminal can know in which area the personal communication network is provided according to the area range information of the personal communication network. In another embodiment, the terminal compares the identifier of the personal communication network broadcasted in a cell supporting the personal communication network with the identifier of the personal communication network obtained from among the first information, and determines the deployed personal communication network. It is possible to know whether the cell supports or not and whether to initiate the personal communication service.

Regarding application information that allows access to a personal communication network (or referred to as allowing use of a personal communication service), application information that prohibits access to a personal communication network (or referred to as prohibiting use of a personal communication service), To be easily understood, a terminal can simultaneously support access of a private communication network and a public communication network. Some applications on the terminal are only allowed to run on the private communication network. On terminals, some applications are only allowed to run under public telecommunications networks. By disposing application information allowing access of the private communication network, the terminal can help trigger access of the private communication network or access of the public communication network when data is generated in the application. In another embodiment, the same goal can be reached by arranging the type of network the application accesses.

Accordingly, even if the current network does not support the personal communication network, the current network can broadcast the redirection information of the personal communication network, and thus the terminal can quickly support the personal communication network after obtaining the redirection information of the personal communication network. It is possible to find a network that supports the personal communication network, thereby reducing the range in which the terminal searches for a network supporting the personal communication network, and improving the efficiency of the terminal searching for a network supporting the personal communication network.

This embodiment mainly describes a process in which a terminal contracting a private communication network performs handover from a private communication network to a public communication network. Referring to FIG. 12, as shown in FIG. 12, the following steps are included.

Step 1: According to the acquired fourth information, when a handover event occurs, the RAN network element confirms that the target cell does not belong to the service area of the private communication network. The RAN network element sends an NG interface message to the AMF, for example an NG handover request or a connection release request where the NG interface is associated with a terminal.

Optionally, the NG interface message includes first mobility information, the first mobility information comprising: an instruction to move from a public communication network to a private communication network, an instruction to move from a private communication network to a public communication network, a source RAN network It may include at least one of a personal communication network identifier supported by the element or source cell, a personal communication network identifier supported by the target RAN network element or target cell, and a network type supported by the target node.

Step 2: AMF sends SM Context Update Request to SMF.

Optionally, includes first movement information.

Step 3: The SMF releases the PDU session or suspends the PDU session according to the first mobility information. SMF sends N4 Session Modification or N4 Session Release to UPF.

Step 4: SMF sends SM Context Update Response to AMF.

Step 5: The AMF sends an NG interface message to the RAN network element.

Step 6: The RAN network element releases the RRC connection of the terminal through an RRC message or places the terminal in an RRC inactive state.

Embodiment 5: A way to disallow roaming is a location update from a private communication network to a public communication network.

This embodiment mainly describes a process in which a terminal of a private communication network that is not allowed to roam in the public communication network initiates a location update in the public communication network. Referring to FIG. 13, as shown in FIG. 13, the following steps are included.

Step 1: The UE sends a registration request message to the target AMF via the RAN network element. A source AMF message is included in the registration request message.

Step 2: The target AMF sends a UE context transmission to the source AMF. Information (ID, type) of the target network is included in the UE context transmission message. Information of the target network is indicated by public transport network information.

Step 3: According to the information of the target network, the source AMF confirms that the terminal has already moved out of the service range of the personal communication network.

The source AMF transmits a PDU session update request or UE location notification message to the SMF. Request PDU Session Suspending or PDU Session Release.

Step 4: SMF sends N4 Session Modify or N4 Session Release to UPF.

Step 5: The SMF sends a PDU Session Update Response to the source AMF.

Step 6: The source AMF sends a UE context transmission rejection to the target AMF. The cause of rejection indicates that the terminal has moved out of the range of the personal communication network.

The target AMF also acquires contract information of the terminal from the UDM and confirms that the terminal is not currently allowed to access the network.

Step 7: The target AMF returns registration rejection to the UE through the RAN node.

Embodiment 6: A way to allow roaming is a handover from a private communication network to a public communication network.

This embodiment mainly describes a process in which a terminal contracting a private communication network performs handover from a private communication network to a public communication network. Referring to FIG. 14 , as shown in FIG. 14 , the following steps are included.

Step 1: According to the acquired fourth information, when a handover event occurs, if the source RAM network element confirms that the target cell does not belong to the service area of the private communication network, the source RAN network element initiates N2 handover .

Step 2: The source RAN network element sends an N2 handover request to the source network. Optionally, first movement information is included in the N2 handover request message.

Step 3: The source AMF sends a PDU Session Context Claim to the H-SMF. Optionally, includes first movement information.

The H-SMF selects a PDU session to be handed over according to the first movement indication information. In one implementation, not all PDU sessions are allowed to hand over from the private communication network to the public communication network.

Step 4: The source AMF selects the target AMF. The source AMF sends a context setup request to the target AMF.

Step 5: The target AMF sends a SM context setup request to the V-SMF.

Step 6: V-SMF selects V-UPF. The V-SMF transmits N4 session setup to the selected V-UPF.

Step 7: The V-SMF sends an SM context establishment response to the target AMF.

Step 8: The target AMF sends a handover request to the target RAN network element.

Step 9: The target RAN network element sends a handover claim confirmation to the target AMF.

Step 10: The target AMF sends a SM context update request to the V-SMF. Requests location update on the N3 interface RAN side of the PDU session.

Step 11: V-SMF sends N4 Session Update to V-UPF.

Step 12: The V-SMF returns the SM context update response to the target AMF.

Step 13: The target AMF sends a context establishment response to the source AMF.

Step 14: The source AMF sends a handover command to the source RAN network element.

Step 15: The RAN network element sends an RRC message to the terminal. A handover command is included in the RRC message.

Step 16: The UE accesses the target RAN network element.

Step 17: The target RAN network element sends a handover notification to the target AMF.

Step 18: The target AMF sends handover completion to the source AMF.

Step 19: The source AMF sends an SM Context Update Solicitation message to the H-SMF.

Since the V-UPF is inserted in the middle, it is requested to update the downlink AN path information of the H-UPF in the above message.

Step 20: H-SMF sends N4 session modification to H-UPF.

Step 21: The H-SMF sends an SM context update response to the source AMF.

After handover is completed, data between the UE and the DN is transmitted through the data path between the target RAN network element, V-UPF, and H-UPF. Session management signaling between the UE and the H-SMF is transmitted through the target RAN network element, the AMF, and the V-SMF.

When a terminal switches from a private communication network to a public communication network, not all private communication services available in the terminal may be able to hand over to the public communication network. The H-SMF directs the RAN network element to determine which private communication services can handover to the public communication network.
